When using the grouped DropDownList and performing a search for a specific element, the DropDownList incorrectly displays the initially shown group instead of the group containing the searched element.

To reproduce the issue: 

1. Open this REPL example: https://blazorrepl.telerik.com/QROrkouK40PFQCUU27
2. Open the DropDownList and type "v" in the filter input field.

When the option "AllowCustom" is enabled for a TelerikComboBox and the user types something above a certain speed, typed characters are lost. Here is a GIF showing the problem on the page https://demos.telerik.com/blazor-ui/combobox/custom-values – I typed "123456", but end up with "1246" instead. In between the input field is showing some weird glitching.

Is there a way to have the TelerikComboBox behave normally, as it apparently did in versions prior to 4.3.0? We noticed this behavior only some time after upgrading from version 4.0.1, where everything still works properly.

Hi,

 documentation missing one extremely "silent" breaking change in grid data binding.

When binding/refreshing(subsequent reload) data to VARIABLE, there is "random" need to call grid.Rebind(); Mostly, when data are loaded outside of the grid, ie by some button, or another component. Used together with selected items and grouping enabled.


<TelerikGrid Data="@GridData" SelectionMode="GridSelectionMode.Single" SelectedItems="..."
						 OnRowClick="@...r"  @ref="GHL" ....>

 

prior v6.0, everything is OK:

protected async Task ReloadGrid(int? xid)
{

GridData= await LoadDatafromservice<TItem>...;

}

After upgrading same code, it silently not displaying data or cras.

new breaking behavior at v6.0  - hotfix, but "ugly one":

protected async Task ReloadGrid(int? xid)
{

GridData= await LoadDatafromservice<TItem>...;

GHL.Rebind(); //required, otherwise grid content(rows) is not update. Later the grid crash when selecting row etc. Old "rows" are still displayed;

}

Its weird to gues, where rebind is needed and where not. Previous versions acting as expected(async - task = no problem).
Make it documented, "what is correct" and when.

Or if it is a bug, please move it out from feature request.

Thanks

Please consider adding to Blazor UI a drop-down treeview component with:

  • multiple selections via checkboxes
  • expand/collapse
  • lazy loading on expand
  • tag mode

Example:

Blazor Dropdown Tree with checkboxes.

Thank you

Hi,

 

Here is my demo DatePicker Demo

In Firefox, after I use the mouse to black all texts out, then DatePicker only selects the month field in the place holder. I expect to select all texts.

In Chrome or Edge, the DatePicker works as expected, after blacking texts out, it selects all texts in the place holder

Could you please check the issue?

 

Thanks and regards,

Tung

The current Column Chooser is not user friendly and requires multiple clicks as well as user training. For these reasons, I would like the option to include a built in Column Chooser in one location, the Grid ToolBar.

When the user drags a third column to the Grid Group Panel, it ends up being second, instead of last. It looks like each new column is inserted at index 1, instead of appended last (when this is the user's intent).

@using Telerik.DataSource

<p>Group by a third column, so that it should come last in the Group Panel:</p>

<TelerikGrid @ref="@GridRef"
             Data="@GridData"
             Pageable="true"
             Sortable="true"

        <GridColumn Field="@nameof(Employee.Name)" />

        <GridColumn Field="@nameof(Employee.Salary)" />
        <GridColumn Field="@nameof(Employee.OnVacation)" />
    </GridColumns>

@code {
    private TelerikGrid<Employee>? GridRef { get; set; }

    private List<Employee> GridData { get; set; } = new();

    private void OnGridStateInit(GridStateEventArgs<Employee> args)

                OnVacation = i % 3 == 0

Hello, I like the Telerik PDF Viewer for Blazor, but it's not supporting Table of Contents (TOC) links.  I would like to request this feature so that there are links in the TOC automatically.  I'm using Blazor WebAssembly.

Thank you for considering my request.

I have a ComboBox that gets data from a remote service, using virtualization. When the PageSize property is big enough (in my case 20), I have issues scrolling down. I'm trying to scroll but it removes the input text.

You can use your own demo examples to replicate this issue. To reproduce the issue, try the ComboBox - Virtualization, in Telerik REPL (Demo)

Need feature parity in the Blazor rich text editor similar to the Angular rich text editor.  Need access to add custom schema elements and tag highlighted text with those new schema elements.

https://www.telerik.com/kendo-angular-ui/components/editor/schema/

currently am able to do this with custom Marks in the angular version.

It would be very nice if the predefined dialogs allowed for us to change the text of the buttons.  For example, being able to change the button text on the prompt dialog to Yes & No, instead of Ok & Cancel.

TlerikDropDownList keyboard navigation works differently from native html select.

In case we have a list with many similar options, for example:
011
021
211
....
In this case with native html select I can type 02 to select 021, but with TlerikDropDownList this would select 211.

If you type swiftly multiple printable characters, the DropDownList keyboard navigation will react only to the first character.

Greetings.

I think I found a minor bug when using the TabStrip component. If you have something like this:

<TelerikTabStrip>
	<TabStripTab Title="First tab">
		<p>First content</p>
	</TabStripTab>
	<TabStripTab Title="Second tab">
		<p>Second content</p>
	</TabStripTab>
	<TabStripTab Title="Third tab">
		
	</TabStripTab>
 </TelerikTabStrip>

And you click the tab without content, it stays selected.

Regards

Greetings.

I was using the FileManager component for a project and wanted to disable some operations since in my use case, it must not be possible to do them. But I was surprized to notice that this apparently cannot be done. So I suggest to add boolean parameters that will allow to disable the following features:

  • new folder
  • renaming
  • searching
  • details pan
  • download
  • upload
  • delete

Of course, the goal here would be to render the user interface accordingly. E.g., if deletion is disabled:

  • remove the Delete entry in the right click menu
  • and never call the OnDelete event.

I have a NumericTextBox inside a Grid EditorTemplate. The edit more is InCell.

The OnChange event of the NumericTextBox will not fire if the user tabs out of the NumericTextBox.

https://dynamic-linq.net/

Please consider refactoring Telerik.DataSource to allow for Dynamic Linq expressions rather than fixed Member.

1. You don't have to reinvent the wheel in creating lambda expressions. You can simplify Telerik.DataSource code to just use Dynamic Linq.

2. Allows support for Sorts & Grouping to be expressions such as "Math.Abs(field ?? 0)" rather than just "field".

Telerik.Blazor.DialogFactory

User types in an input string, but they have to click 'ok' with the mouse to proceed - typing enter does nothing
